RE: [Digital BW] 4800 UC QTR profiles

2005-08-10 by Daniel Staver

While I was still working on Quadprofile N_OF_TONER_PARTS and all the other
_PARTS settings were completely ignored. I made it so that Quadprofile would
find the number of inks based on what was actually used in the ink
descriptor. The number of unused inks were also determined automatically, so
that's not strictly neccessary to have in the file either. I think these
settings were left in there only because of backwards compatability with
older versions.

Higher values for highlight and shadow decreases density in that part of the
curve. Lower values increases density. Try to create a BO curve and watch
the generated curve shape each time you change a setting. This gives you a
pretty good idea of how the different settings work.
